BIMS: A Legacy of Excellence
BIMS has been dedicated to heating, cooling, and mechanical services since 1980. The company was founded by HVAC contractor Randy Bellomy. He launched the business with just $200, an old truck, and a determination to do things the right way. Working out of his home, Randy built his reputation on a simple promise:
"If it heats or cools, we’ll work on it."
For decades, BIMS provided residential, commercial, and industrial HVAC-R services under that philosophy. Eventually, Randy’s son, Grant Bellomy, recognized that the industry and customer needs were changing. Grant grew up in the business. He spent his childhood around service trucks, tools, and rooftops. As he got older, he began imagining new ways to expand and modernize the company.
In 2018, after purchasing the business from his father, Grant led a major transformation. BIMS shifted its focus toward commercial and industrial HVAC-R—larger, more complex systems that demand advanced technical knowledge. Along with this evolution came a fresh identity:
BIMS—Bellomy Industries & Mechanical Services—a name that better reflects the company’s mechanical expertise and capability to support large-scale, mission-critical facilities.
Today, Grant’s vision is fully realized. BIMS is a trusted, highly specialized mechanical contractor serving the DFW region. Our technicians bring decades of hands-on experience. They hold Texas Air Conditioning Contractors Licenses (TACLs), ensuring every project meets the highest professional and regulatory standards.
From humble beginnings to a respected leader in advanced HVAC-R solutions, BIMS continues to honor its roots. The company embraces innovation—keeping businesses comfortable, productive, and running at their best.

BIMS Stands Apart from Other Dallas Industrial HVAC-R Contractors

We currently offer a wide variety of non-residential services in DFW and the surrounding metroplex, including geothermal heat pumps, air purification, pneumatic controls, warehouse heaters, and scientific refrigeration. No need for multiple companies to service multiple systems. If you have a commercial or industrial HVAC need, BIMS has a solution.
